Abstract in brief

Understanding reaction pathways is crucial for optimizing solid-state reactions, which have been challenging to study due to their complexity and technical limitations.
Using advanced synchrotron X-ray techniques, researchers explored solid-gas reduction mechanisms in layered perovskite SrFeO, highlighting its potential as an environmental catalyst.
The study found that while pristine SrFeO shows a predictable structural evolution, a Pd-loaded sample experiences a sudden change in its reaction pathway just before a phase transition, indicating a shift in the rate-determining step of the reaction.
